Description

  The present invention relates to grafting tools for moss such as cucumber, melon and watermelon, and other seedlings such as eggplant and tomato.

Raised seedlings (hogi) of cucumbers, melons, watermelons, etc. are grafted and grown on seedlings (rootstocks) such as nanban and evening faces. The present applicant has proposed a grafting tool made of an elastic plastic cylindrical body having a vertical split on one side, for example, in Patent Document 1 below.
Utility Model Registration No. 2504375

  The seedling grafting tool proposed in Patent Document 1 is made of an elastic plastic cylinder having a vertical split on one side, and has an upward diameter at the upper end of the inner periphery and a downward diameter at the lower end. The taper which expands is provided, and the attachment member to a support | pillar is provided in the position different from the crack on the peripheral side of a cylindrical body. As a result, it can be accommodated in the inner circumference of the cylindrical body without damaging the cut end of the hogi while guiding the hogi with a taper, so that the rootstock and the hogi can be erected efficiently. . Furthermore, water irrigated by the taper at the upper end of the cylindrical body could be stored, drying of the cut end of the hogi could be suppressed, and the viability could be further improved. In addition, after grafting, since the seedlings were connected to the pillars standing on the ground with the mounting member on the circumferential side of the cylindrical body, it is possible to prevent the root and safflower survival from being hindered by wind and vibration, etc. It has become possible to eliminate the trouble of connecting the seedlings to the support with a string.

  Note that as the grafted seedling grows and thickens, the cylindrical body expands the cracks in the vertical direction and does not inhibit the growth of the seedling. And since it finally spreads out and removes from the young seedling, it is possible to eliminate the need to remove it after taking it on.

  However, in conventional grafting tools for seedlings, if the sap from the rooting surface of the rootstock and hogi is collected on the inner periphery of the cylindrical body after grafting, this sap becomes a factor that causes bacteria to propagate and the grafted seedlings are Since problems such as corrosion may occur, keep a constant distance between the grafted part including the roots and roots of the roots and the inner peripheral surface of the cylindrical body, so that the juice does not accumulate on the inner periphery of the cylindrical body Improvements are needed. On the other hand, if the space between the grafted part including the roots and the roots of the rootstock and the inner peripheral surface of the cylindrical body is narrowed, the movement of the seedlings due to wind and vibration can be further suppressed after grafting. There is also the fact that further improvements in the efficiency of occupying wood and hogi are expected. Furthermore, there has been a demand to further improve the efficiency of the grafting work itself by inserting rootstock and hogi into the cylindrical body.

  Accordingly, in view of the above circumstances, the present invention improves the previously proposed grafting tool so that the juice coming from the rooting surface of the rootstock and the hogi after grafting does not collect on the inner periphery of the cylindrical body, By narrowing the space between the grafted part including the planting part of the tree and the inner peripheral surface of the seedling grafting tool, it is possible to further improve the efficiency of survival of rootstocks and spikelets. It is an object of the present invention to provide a grafting tool for young seedlings that can be further improved in efficiency.

  In order to solve the above-mentioned problems, a seedling grafting tool according to the present invention is a seedling grafting tool composed of an elastic plastic cylindrical body having a vertical split on one side. One or more inward ribs penetrating in the direction are provided.

  Then, at least one of the upper end of the rib and the lower end of the rib is protruded from the cylindrical body, and an inclined surface is formed on the inner side of the protruding rib so as to expand from the cylindrical body side toward the tip of the rib. It is preferable to do.

  In the present invention, since one or more inwardly extending ribs penetrating in the vertical direction are provided on the inner peripheral surface of the cylindrical body of the seedling grafting tool, there is a step between the inner peripheral surface of the cylindrical body and the rib. It is possible to prevent the juice from the roots and hogi from being attached after the grafting flows downward through this level difference and collect on the inner periphery of the cylindrical body. In addition, since the grafted seedling can be supported by this one or more ribs, that is, it can be supported by one or more points, a conventional seedling grafting tool must be supported by its inner peripheral surface. As compared with the above, it is possible to greatly expand the range of the seedling thickness that can be applied in one size of the seedling grafting tool. In addition, since the space between the grafted part including the roots and roots of the rootstock and the inner peripheral surface or rib of the cylindrical body can be narrowed, the movement of seedlings due to wind and vibration is suppressed, and The efficiency of engrafting can be further improved.

  In addition, since at least one of the upper end of the rib and the lower end of the rib is protruded from the cylindrical body, an inclined surface is formed on the inner side of the protruding rib so as to expand from the cylindrical body side toward the tip of the rib. Since it is easy to insert rootstocks and scrubs into the inner periphery of the cylindrical body, it is possible to perform grafting work while confirming the insertion positions of rootstocks and scorches into the inner periphery of the cylindrical body. It is also possible to further improve the efficiency of the work itself.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is a perspective view of a seedling grafting tool in one embodiment according to the present invention, FIG. 2 is a plan view of the seedling grafting tool in one embodiment according to the present invention, and FIG. 3 is according to the present invention. FIG. 4 is a cross-sectional view taken along the line AA of FIG. 2, and FIG. 4 is a front view of a seedling grafting tool in one embodiment. FIG. 5: is a perspective view which shows the state which grafts a rootstock and a safflower regarding the grafting tool of the young seedling in one Embodiment which concerns on this invention.

The seedling grafting tool in one embodiment according to the present invention is, as shown in FIGS. 1 to 4, a plastic body having an appropriate elasticity, for example, an injection molding of EVA, for example, a cylindrical tubular body 1, On one side, a vertical split 2 that reaches the inner peripheral surface 3 of the cylindrical body 1 is formed. In particular, the inner circumferential surface 3 of the cylindrical body 1 is provided with inward ribs 10 penetrating in the vertical direction at one or more locations, for example, three locations at equal intervals in the circumferential direction. A step is formed between 3 and the rib 10. The three ribs 10 project the upper end 11 and the lower end 12 from the upper end surface 4 and the lower end surface 5 of the cylindrical body 1, respectively. On the inner side of the upper end 11 and the lower end 12 of the three protruded ribs 10, inclined surfaces 13 and 14 are formed to expand from the cylindrical body 1 side toward the tip of the rib 10, respectively.
The cylindrical body 1 may be a polygonal cylindrical shape other than the cylindrical shape. As an example, the dimensions of the cylindrical body 1 are about 14 mm, the outer diameters of the upper end surface 4 and the lower end surface 5 are about 9 mm, and the inner diameters of the upper end surface 4 and the lower end surface 5 are about 2 mm.

  A mounting member 7 is provided on the outer peripheral surface 6 of the cylindrical body 1 at a position different from the crack 2. The mounting member 7 includes an arm 8 extending horizontally from the upper end surface 4 of the cylindrical body 1 and a ring 9 provided at the tip of the arm 8. The attachment member 7 is for holding a support column standing from the ground and preventing the seedlings grafted by the cylindrical body 1 from being overturned by wind or vibration. Instead of the ring 9, a C-shape having a crack or other structures may be used.

Here, based on FIG. 5, the grafting operation | work using the seedling grafting tool of one Embodiment which concerns on this invention is demonstrated.
First, the upper end portion of the rootstock 20 obtained by cutting and removing the upper portion obliquely is aligned with the inclined surface 14 of the lower end 12 of the rib 10 protruding from the lower end surface 5 of the cylindrical body 1, and along the inclined surface 14. It is housed in the lower half of the inner periphery of the cylindrical body 1. At this time, the inclined upper end (or the lower end) of the oblique cut at the upper end of the rootstock 20 is preferably directed to either the crack 2 or the attachment member 7 of the tubular body 1. Further, the upper end portion of the rootstock 20 can be accommodated in the lower half portion of the inner periphery of the cylindrical body 1 with a light force.
Subsequently, the lower end portion of the hogi 30 removed by obliquely cutting the lower portion is aligned with the inclined surface 13 of the upper end 11 of the rib 10 projecting from the upper end surface 4 of the cylindrical body 1, and along the inclined surface 13. The tube 1 is inserted from above. At this time, it is preferable that the inclined lower end portion (or upper end portion) of the oblique cut at the lower end of the hogi 30 is directed toward the crack 2 or the attachment member 7 similarly to the rootstock 20. Further, the lower end portion of the hogi 30 can be inserted into the upper half of the inner periphery of the tubular body 1 with a light force.
Then, the oblique cut at the upper end of the rootstock 20 and the oblique cut at the lower end of the hogi 30 are made to face each other complementarily in the inner periphery of the cylindrical body 1 and are alive. Further, the ring 9 of the mounting member 7 is connected to a support post stabbed on the ground to obtain a state as shown in FIG.
The above grafting work is very much performed by pressing and fitting the cylindrical body 1 one after another to one of the many rootstocks 20 and then inserting the hogi 30 from the top of the cylindrical body 1 to one. It can proceed efficiently.

  The seedlings that have been grafted by the seedling grafting tool in one embodiment according to the present invention are supported by the three ribs 10 provided on the cylindrical body 1. The juice coming out from the living part 40 where the oblique cut at the upper end of the rootstock 20 and the oblique cut at the lower end of the hogi 30 face each other is between the inner peripheral surface 3 of the cylindrical body 1 and the rib 10. Since a step is formed at the bottom of the cylindrical body 1, it flows downward from the inner periphery of the cylindrical body 1 (to the rootstock 20 side) through this step.

  Therefore, the seedling grafting tool in one embodiment according to the present invention is provided with three inward ribs 10 penetrating in the vertical direction on the inner peripheral surface 3 of the cylindrical body 1 at equal intervals in the circumferential direction. By forming a step between the inner peripheral surface 3 of the shape 1 and the rib 10, the sap from the roots 20 and the survival part 40 of the hogi 30 after grafting is transferred from the inner periphery of the tubular shape 1 to the outside through this step. It is possible to prevent the gas from flowing down downward and collecting on the inner periphery of the cylindrical body 1. Furthermore, since the rib 10 is provided, it is possible to narrow the space between the grafted portion including the root portion 20 and the survival part 40 of the hogi 30 and the inner peripheral surface 3 or the rib 10 of the tubular body 1. The movement of the young seedling due to vibration or the like can be suppressed, and the efficiency of activating the rootstock 20 and the hogi 30 can be further improved.

  Further, the upper end 11 and the lower end 12 of the rib 10 are protruded from the upper end surface 4 and the lower end surface 5 of the cylindrical body 1, and the inner side of the protruding rib 10 is directed from the cylindrical body 1 side toward the tip of the rib 10. Since the inclined surfaces 13 and 14 to be expanded are formed, the rootstock 20 and the hogi 30 can be inserted into the inner periphery of the cylindrical body 1 with a light force. Furthermore, since the grafting work can be performed while confirming the inclined surfaces 13 and 14 at the tips of the ribs 10 at the insertion positions of the rootstock 20 and the hogi 30 to the inner periphery of the cylindrical body 1, the grafting work becomes easy. Further, it is possible to further improve the work efficiency.

In addition, a seedling grafting tool according to another embodiment of the present invention will be described below.
FIG. 6 is a perspective view of a seedling grafting tool according to another embodiment of the present invention, FIG. 7 is a plan view of the seedling grafting tool according to another embodiment of the present invention, and FIG. It is sectional drawing in the -B line.

  As shown in FIGS. 6 to 8, the grafting tool for seedlings according to another embodiment of the present invention is a cylindrical shape injection-molded with a plastic having an appropriate elasticity, for example, EVA, as in the first embodiment. A cylindrical body 1 is formed, and on one side thereof, vertical cracks 2 that reach the inner peripheral surface 3 of the cylindrical body 1 are formed, and the inner peripheral surface 3 of the cylindrical body 1 is provided at three positions equally spaced in the circumferential direction. An inward rib 10 penetrating in the vertical direction is provided, and a step is formed between the inner peripheral surface 3 of the cylindrical body 1 and the rib 10. On the other hand, unlike the above-described one embodiment, the upper end 11a and the lower end 12a of the three ribs 10 are configured not to protrude from the upper end surface 4 and the lower end surface 5 of the cylindrical body 1. In addition, inside the upper end 11a and the lower end 12a of the three inwardly located ribs 10 located on the inner peripheral surface 3 side of the cylindrical body 1, respectively, spread from the inner side of the cylindrical body 1 toward the tip of the rib 10. Inclining surfaces 13a and 14a are formed.

  Then, in the grafting tool for young seedlings in other embodiments, inward ribs 10 penetrating in the vertical direction are equally spaced in the circumferential direction on the inner peripheral surface 3 of the cylindrical body 1 as in the first embodiment. Since three steps are provided and a step is formed between the inner peripheral surface 3 of the cylindrical body 1 and the rib 10, the juice coming from the roots 20 and the survival parts 40 of the hogi 30 after grafting allows the cylindrical body 1 to pass through these steps. It is possible to prevent the gas from flowing downward from the inner circumference to the outside and collecting on the inner circumference of the cylindrical body 1. Furthermore, since the rib 10 is provided, it is possible to narrow the space between the grafted portion including the root portion 20 and the survival part 40 of the hogi 30 and the inner peripheral surface 3 or the rib 10 of the tubular body 1. The movement of the young seedling due to vibration or the like can be suppressed, and the efficiency of activating the rootstock 20 and the hogi 30 can be further improved.

  In addition, since the inclined surfaces 13a and 14a are formed inside the upper end 11a and the lower end 12a of the rib 10 so as to expand from the inner side of the cylindrical body 1 toward the tip of the rib 10, the rib 10 is formed on the cylindrical body 1. Even if it does not protrude from the end face 4 and the lower end face 5, the rootstock 20 and the hogi 30 can be inserted into the inner periphery of the tubular body 1 with a light force. Further, the grafting operation can be performed while confirming the inclined surfaces 13a and 14a at the tips of the ribs 10 at the insertion positions of the rootstock 20 and the hogi 30 to the inner periphery of the cylindrical body 1, and the grafting operation becomes easy. Further, it is possible to further improve the work efficiency.

As mentioned above, although two embodiment which concerns on this invention was explained in full detail, this invention is not limited to the said embodiment. The present invention can be modified in various ways without departing from the scope of the claims.
For example, in the above description, the example in which three inward ribs penetrating in the vertical direction are provided on the inner peripheral surface of the cylindrical body, but there is a step between the inner peripheral surface of the cylindrical body and the rib. As long as the juice from the grafted seedlings can be drained from the inner periphery of the cylindrical body to the outside, one or more inward ribs penetrating in the vertical direction according to the convenience of the manufacturing equipment etc. Can be provided. In addition, an example has been shown in which both the upper end and the lower end of the rib are protruded from the upper end surface and the lower end surface of the cylindrical body, but when at least one of the upper end and the lower end of the rib is protruded from the cylindrical body. However, since at least one of the rootstock and the hogi can be easily inserted into the inner periphery of the cylindrical body, it is possible to further increase the efficiency of the grafting work itself.

  Further, in the above description, since the oblique cuts of the rootstock and the hogi face each other complementarily in the inner periphery of the cylindrical body, the inclined upper end and lower end of each cut are either cracks or attachment members. However, the upper and lower ends of the cylindrical body may be provided with marks at a phase of 180 °, and the inclined upper and lower ends of the oblique cuts of rootstock and hogi may be directed to the marks. You may provide a mark in the intermediate position of the height of the form in the up-down direction. In addition, if the cylindrical body is molded from transparent plastic, it is possible to see whether the diagonal cuts of the rootstock and hogi are facing each other on the inner circumference of the cylindrical body correctly. Can be ensured.
